| 英文摘要 | the molar heat capacities of an aqueous li2b4o7 solution were measured with a precision automated adiabatic calorimeter in the temperature range from 80 to 356 k at a concentration of 0.3492 mol . kg(-1). the occurrence of a phase transition was determined based on the changes in the curve of the heat capacity with temperature. a phase transition was observed at 271.72 k corresponding to the solid-liquid phase transition; the enthalpy and entropy of the phase transition were evaluated to be delta h-m = 4.110 kj . mol(-1) and delta s-m = 15.13 j . k-1 . mol(-1), respectively. using polynomial equations and the thermodynamic relationship, the thermodynamic functions [h-t-h-298.15] and [s-t-s-298.15] of the aqueous li2b4o7 solution relative to 298.15 k were calculated in the temperature range 80 to 355 k at intervals of 5 k. values of the relative apparent molar heat capacities of the aqueous li2b4o7 solution, c-p,c-phi, were calculated at every 5 k in the temperature range from 80 to 355 k from the experimental heat capacities of the solution and the heat capacities of pure water. |
